Abstract

Immunohistochem. examn. of the galaninergic and the diffuse endocrine systems of the alimentary canal of 3 catfish species, Ameiurus melas, Silurus glanis, and Clarias gariepinus, showed the presence of galanin-like immunoreactive endocrine cells in the stomachs and the proximal intestines and a galanin-like immunoreactivity within the enteric intramural neurons. The 3 species differed notably in the relative abundance of galaninergic neurons of the digestive system. A galanin-like peptide was detected in a high no. of nerve bundles and nerve fibers running through the exocrine parenchyma and the endocrine islets of the pancreas of all 3 species. It is conceivable that the galaninergic system in these species plays a role in regulating gut muscle activity, in modulating mucosal secretive and absorptive processes, and in controlling pancreatic hormone secretion.
